Paging control method and paging control system in communication system
First Claim
1. A paging control method of a communication system that selectively provides one of communication services implemented by integrating a plurality of communication systems, the paging control method comprising:
- a first step of transmitting a paging signal from each of the plurality of communication systems to a terminal; and
a second step of receiving the plurality of paging signals by said terminal, and of selecting a desired communication system for use by said terminal from said plurality of communication systems in accordance with information contained in the plurality of paging signal received.

Abstract
Efficient paging control is achieved in a communication system that selectively provides one of communication services implemented by integrating a plurality of communication systems. Before transmitting a downlink signal to a terminal, a gateway requests each of the communication systems to transmit a paging signal to the terminal. Receiving the paging signals transmitted from the communication systems, the terminal selects a communication system A with the lowest communication cost in accordance with communication cost information contained in the paging signal. The terminal sends a request for connection to the selected communication system A. As a result, the communication system A transmits the downlink signal to the terminal.
